- 下載&編譯
git clone [email protected]:llvm/llvm-project.git -b release/11.x
cd llvm-project && mkdir build && cd build
cmake -G "Unix Makefiles" ../llvm -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DLLVM_TARGETS_TO_BUILD=AArch64;X86;
make -j8
sudo make install
如果只要編譯clang，在cmake命令添加定義 -DLLVM_ENABLE_PROJECTS=clang;
LLVM_ENABLE_PROJECTS可用的項目有
clang;clang-tools-extra;compiler-rt;debuginfo-tests;libc;libclc;libcxx;libcxxabi;libunwind;lld;lldb;mlir;openmp;parallel-libs;polly;pstl
例如LLVM_ENABLE_PROJECTS=clang;clang-tools-extra;libc;libclc;libcxx;libcxxabi;lld;lldb;
默認會編譯所有平臺，可以通過LLVM_TARGETS_TO_BUILD指定平臺，可用平臺有AArch64, AMDGPU, ARM, BPF, Hexagon, Mips, MSP430, NVPTX, PowerPC, Sparc, SystemZ, X86, XCore
